Networking of Computer: Cable Punching


Now I am sharing the networking process. If we can know how to built or connect a computer with another computer then, we will do many work together and we know that sharing works would be acceptable and we can do every work perfectly.

I narrate
Network Cable Setup : We can be connected a computer with another computer by Twisted Pair cable. Manually Twisted Pair Cable has partly eight cables into cover of the cable and every cable is various colors. We need RJ45 connector to connect cable. At first connect RJ45 with Twisted Pair Cable by Punching. It is called Cable Punching.

Twisted Pair Cable’s cable
  1. Orange White  =================
  2. Orange             =================
  3. Blue White       =================
  4. Blue                  =================
  5. Green White   =================
  6. Green               =================
  7. Brown White   ================= 
  8. Brown              =================              

Now, we connect with two PC that means we do not use HUB. So the cable punching’s crossing is in below-----

      1st Side                                           2nd Side
1. Orange White                             1. Green White  
2. Orange                                        2. Blue
3. Green White                              3. Orange White
4. Green                                          4. Green
5. Blue White                                 5. Blue White
6. Blue                                            6. Orange
7. Brown White                             7. Brown White
8. Brown                                        8. Brown


Now, I am narrating how to connect with more computers for networking by Twisted Pair Cable. We should to use a HUB or a Switch. Obviously it is easy and cable color would be punched at same colored cable. In below the connection process has been written ……

1st Side                                                2nd Side
      1. Orange White=================1. Orange White
      2. Orange           =================2. Orange

      6. Green            ================= 6. Green
      7. Brown White ================= 7. Brown White
      8. Brown             =================8. Brown

Computer Software and Hardware Name

Some name of Computer’s symbol which are very important. We can not think a complete computer without these components. I try to narrate every symbol’s name and shortcut-full name.


MHZ,GHZ & KHZ : MHZ’s  elaboration is Mega Hertz and GHZ’s elaboration is Giga Hertz and KHZ’s elaboration is Kilo Hertz. Every Hertz are measurer which are measured frequency by Giga, Mega and Kilo Hertz.

Cash Memory : It is memory which is increased usual speed or performance of computer. Basically, this memory stays at processor and exhibit instruction of processor. Cash Memory is tow kind …. 1) Disk Cash 2) Memory Cash
                                                   
Plug & Play : It is a power which is played when plug a device with a computer and then operating system can recognize the connected device, like---- a Monitor, Optical Drive etc.

Peripheral :  Peripheral is a device, which is connected with computer. Example: Modem, Printer etc.

Backup : It is a stored file which is copied from a memory for future and it is called Backup.

Ranch Mark :  Ranch Mark is some examination, which is compared performance of Computer Hardware or Computer Software.

Computer Virus : Virus’s elaboration is Vital Information Resource Vender Size. It is a program which is damaged a computer at short time. It is discovered by Fred Cohen.

Internet : Internet’s elaboration is Interconnection Network.  It is a system which extended to the whole world. Basically it is an easy way to communicate with each other.

Computer Network : It is a connection which is connected computer with computer to share data.

Digital : Digital Word is discovered from Digit. Digital is called to a method to process, to save and to reveal by Binary Digits.

Computer Hardware : Each elements or devices of Computer are called Computer Hardware. 

Computer Software : Computer could not be do something by own power. So, need some instruction or programs. Every programs are called Software.

Compress : If a file would be large then we need to compress.
